Urubuga rwitwa PON rugizwe nibice bitatu:OLT, ODN naONU.AnOLTigikoresho giherereye kumurongo wa topologiya. Igera kumurongo wa serivise nyinshi hejuru na serivisi zabakoresha benshi hepfo binyuze muri ODN. Nibyingenzi byingenzi byo gukusanya serivisi no gukwirakwiza.OLTicyarimwe imenya ibikorwa byinshi byo kuyobora imiyoboro nko kugenzura, kuyobora, kuringaniza nibindi kubikoresho byabakiriyaONU.OLTibikoresho nibyo shingiro ryumuyoboro wa PON haba muburyo bwa rezo y'urusobe cyangwa imikorere y'urusobe. Hamwe na serivise nyinshi kandi nyinshi nka enterineti, videwo ya 4K IPTV, serivise zo murugo zifite ubwenge, imishinga mito n'iciriritse imishinga yihariye, ijwi rya IMS, hamwe na terefone igendanwa bikorerwa kumurongo wa PON, icyifuzo cyumurongo hamwe nurwego rwo kunonosora. imiyoborere ikomeje kwiyongera .Iterambere ryikoranabuhanga rya PON no kohereza no kwihinduranyaOLTibikoresho bigira uruhare runini mugutezimbere imiyoboro yagutse.
Isesengura ryimiterere ya PON
(1)OLTkohereza ibikoresho
UwitekaOLTibikoresho by'abakora mu gihugu ahanini byoherejwe mu 2006, kandi byakoreshwaga cyane cyane kugirango PON + DSL igere mu cyiciro cya mbere. Kuva mu 2009, FTTH yoherejwe ku ntera nini mu myaka irenga 10. Ukurikije umurongo wa enterineti, ubushobozi bwo guhinduranya imashini yose, hamwe no gushyigikira ikarita yubuyobozi bwa PON, hari ibisekuruza 2 ~ 3 byibicuruzwa bikoreshwa murusobe rwubu. ibikorwa byurusobe bigezweho bigera kuri 40G / ahantu, kandi byose bishyigikira 10G EPON na XG-PON1.
(2) Ikoreshwa rya tekinoroji ya PON
Hamwe nogukoresha buhoro buhoro gukoresha tekinoroji ya 10G PON, amakarita ya PON yagenwe naOLTibikoresho murusobe rwubu bigabanijwemo ubwoko bune: EPON, GPON, 10G EPON na XG-PON, muri byo EPON na GPON nibyo byingenzi.
Mu rwego rwo guteza imbere ibipimo ngenderwaho bya EPON na China Telecom na China Unicom, umushoramari wo mu gihugu EPON agurishwa mbere yimyaka 2 kugeza kuri 3 ugereranije na GPON. Mbere ya 2013, ubwubatsi bwari bwiganjemo EPON, hanyuma, kubera ibyiza bya GPON mugari, byagiye bifata umwanya wiganje muriOLTkubaka. Uhereye kubitekerezo byubu byoherejwe kumurongo, iOLTibikoresho bya China Unicom na China Mobile ni GPON, naho Ubushinwa Telecom ni EPON.
10G PON Kubaka byatangiye ahagana mu 2015. Nkuko igiciro cya 10G optique module ihora ari hejuru, igiciro cya 10G PON ONT nikubye inshuro 5 icy'ibisanzwe EPON / GPON. Mubidukikije bigezweho aho abashoramari batanga ama terefone kubakiriya, kandi ibyifuzo byubucuruzi biri munsi ya 100 Mbit / s, abashoramari bose bakomeye bafite amakenga kubijyanye no kohereza no gukoresha 10G PON. Kugeza ubu, uburyo bwo kubaka 10G PON bukoreshwa cyane cyane muri 10 GPON + LAN na FTTH yoherejwe.10 GPON + LAN ahanini ni uguhindura selile LAN isanzwe, umuyoboro hamwe numuyoboro wa PON + LAN. Ku ruhande rumwe, ikemura ikibazo cyumuvuduko udahagije uterwa numubare munini wabakoresha; kurundi ruhande, kubera ko abakoresha benshi basangiye igiciro cya module optique muri MDU, igiciro rusange cyiyongera gake ugereranije na PON + LAN, bityo rero gifite porogaramu nini, kandi 10G PON na XG-PON byombi byemewe. Kubaka 10G PON FTTH ni umushinga wicyitegererezo ukorwa nabakozi batandukanye. Intego nyamukuru nukumenyekanisha no kugenzura ibicuruzwa bya 10G PON FTTH.
Ibyavuzwe haruguru nibisobanuro byuburyo rusange bwurusobe rwa PON. Ibicuruzwa byurusobe rwa Shenzhen HDV Photoelectronic Technology Co., Ltd. nibikoresho byose bikorerwa hafi ya PON, harimoONUurukurikirane /OLTurukurikirane / optique module ikurikirana / transceiver ikurikirana nibindi.
